摘要： A computer graphic apparatus uses a method and apparatus to approximate a polygonal line of a plurality of line segments (L.sub.1, L.sub.2 . . . ) to a curve (X). The curve is divided into two curve portions (P.sub.10 P.sub.11, P.sub.11 P.sub.02) at a division point (P.sub.11). An error (e) between a line segment (P.sub.01 P.sub.02) linking the start and end points (P.sub.01, P.sub.02) of the curve and the division point is compared with a predetermined value (V.sub.th). When the error is small, the line segment is treated as one part of the polygonal line, but in another case, the above-mentioned process is repeated.

摘要： Disclosed is an production method for plasma chemical vapor deposition (CVD) of amorphous silicon films providing improved throughput and film yield. According to the present invention, a glow discharge is generated in a reaction chamber containing a gaseous silicon-containing compound, such as monosilane (SiH.sub.4) or tetraflourosilane (SiF.sub.4), by the imposition of an electric field between a pair of spaced-apart electrodes within the chamber. The electric field is established by connecting an appropriate DC or high frequency driving voltage to one of the pair of electrodes and ground potential to the other. In the case where a high frequency driving voltage is used, connection to the driven electrode is made through a coupling capacitor, and the frequency of the driving voltage is selected such that a DC potential develops between the pair of electrodes. Substrates on which amorphous silicon films are to be deposited are positioned adjacent to each one of the electrodes, and the connections for the driving voltage and ground to the electrodes are periodically reversed during film deposition. In an alternative embodiment of the invention, multiple pairs of electrodes are arranged within the reaction chamber.

摘要： In a system for reproducing an image pattern data, a decision point designation means exclusively designates a decision point at the corresponding coordinate position in a coordinate region of image pattern reproduction in divisional coordinate regions when a decision point extracted based on a region decision data obtained by region decision means is located in a region of the first kind, exclusively designates a decision point at the scan starting point of a coordinate region of image pattern reproduction when the extracted decision point is located in a region of the second kind, designates no decision point when the extracted decision point is located in a region of the third kind, and, based on the designation by the decision point designation means, a shading of dots of the image is carried out.

摘要： A data processing apparatus includes a CPU, a memory, and logic operation hardware. When a predetermined instruction code is identified, the logic operation hardware executes an arithmetic operation using data stored in the memory, while the CPU processes the same data. The logic operation hardware then writes the result of the arithmetic operation instead of the data processed by the CPU.
